Originally posted by jrforman Originally reported mine as clear. Need to revise that. Was checking for dust today, and noticed the stains. I have gone back to the original pictures I took when problem was first reported and they aren't there. Needless to say I am confused as to how they are now appearing. I got my camera in Mid September so it was one of the first. And yes, attempted to clean them. They wouldn't move....
Same here, new stains are appearing. I initially thought I had some dust spots next to the stains, so I used a Rocket Blower to clean the sensor. When I checked again, not only were the "dust spots" still there in exactly the same places, but the string of pearls suddenly had some new dots.
I went back to the pictures I took on the very first day I received the K-5 back in November. There's a very convenient shot with tons of blue sky in it taken at F16. That picture is entirely blemish-free. I scrutinized it to be sure. Also, I've run the Dust Alert feature on the camera at least weekly. It never registered any spots initially. Now it registers the stains consistently.
It's entirely possible that some of those people who have reported stain-free sensors are in for a bad surprise down the road.
